Referring to the drawings, which illus trote the preferred 'form ofin),r invention, A. designates the iixed rim on the telly of the gnatestlie deinountable rim that surrounds tbe iiXe-d rim. Said deinonntablerim consists oi a. longitudinal split nieniber Composed of two portionsl :ind l that are provided with flanges for en gaging tbe bends 'on tbeouter easing' 'of o. pneumatic tire, as shown in Fig. E, seid portionsand l. being adapted to be spread apart or seperated Fig. 4i, so as toenable the inner tube ol the tire to be removed :troni the outer casingor arranged inside of the easing Without disconnecting the easing .fromthe portions l and la oi the demonntable rim. Villien the two portions land la oii the deinenntA able rini are in normal position, shown in Fig.3, they iorni a longitudinally split rim ot approximate elini'nielsliapein cross section wliose side flanges snugly,7 embrace the beads on theouter easing of the. tire. Said portions :ire lield together byineinbers, hereinafter described, that pass trains verselj,7 throughsaid portions and they are also'provideifl with cooperating parteWliioli. are embraced by devices on the lined rim il that tend toprevent the portions l and l of the deinounteble riin fi-oni spreadingapart, said devices und parts also eoperatn ingwith e; eli other to holdthe deinountable riin centered with relation to tne iiized riin andprevent the cle-mountable riin from moving oireuxnierentiolly in onedweetion`r ln tbe forni o' my invention herein shown the hold thedeniountable rim laterally, as shown in lOB ` rim is used on a leftwheel.

' iiXed rim A is provided with a plurality of "spaced blocks or devices8, each of which has a longitudinaily-inclined top face, as shown inFig. 1, that is substantiallyV-shaped in cross section. as shown in Fig.5. The two portions 1 and 1a of the demountable rim 1b are provided ontheir' inner sides with cooperating parts 2 and 2a which form aplurality Aof spaced blocks or projections on the inner side o f thedemountable rim when the portions 1 and a are in their normal position,as shown in Fig. 5, the blocks on the demountable rim, formed by thecooperating parts 2 and 2, being inclined longitudinally oppositely tothe blocks 3 on the fixed rim and being of such cross-sectional shapethat they will conform to the top faces of the blocks 3 on the fixed rimon which they bear when the demountable rim is in operative position,thus forming a structure in which the demountable rim is provided with aplurality of spaced devices, each of which embraces a pair ofcooperating parts in a longitudinally split demountable rim. Thecooperating parts 2 and 2a on the demountable rim are preferably sodesigned that the de- ;nountable rim can be used either on a right or ona left wheel, said parts 2 and 2al being tapered longitudinally inopposite directions from the transverse center of sam, as shown in Fig.1, and thus virtually forming two sets-of oppositely-inclined blocks,one set of which cooperate with the blocks 3 on the fixed rim when thedemountable rim is used on a right wheel and the other set coperatingwith the blocks 3 when the denpmntable After the two portions 1 and 1aof the demountable rimhave been connectd together' in a mannerhereinafter described the demountable rim B .is slipped sidewise overthe fixed rim and then moved circumferentially to the left, looking atFig. 1, so as to cause the pairs of cooperating parts 2 and 2a on theinner side of the demountable rim to engage the blocks 3 on the fixedrim, thereby causing the demountable lrim to be centered with respect tothe fixed rim and held securely against [circumferential movement to theleft, looking at Fig. 1,

Various means may be'employed for locking the demouiitable riminoperative position and for pireventing it from movingcircumferentially in the opposite direction,

namely, to the right, looking at Fig. 1, but

A'outer ends of the recesses 5 in the parts 2,

the means that` T prefer to use for thimspurpose consists a lockingmember shogvn in. broken lines in Fig. 1 that is arranged 'be- `tweenthe two'rims A and B at such a point matically takes up any slightcircumferential play or movement that develops between the rims. f

The two` portions 1 and 1a of the deinountable rim are securedtogether', primarily, by fastening members al. that extend transverselyof said portions and prevent them from separating laterally or spreadingapart. It is immaterial, so far as my broad idea is concerned, how thetransverselydisposed fastening members Li are combined with the twoportions l and 1EL of the rim, but I prefer to mount the fasteningmembers -L in the cooperating parts 2 and 2 on the inner side of thedemountable rim B, it being immaterial whether a. fastening member 4 iscombined with each pair of parts 2 and 2'l or only with a few of saidpairs of parts. The fastening members a preferably consist of bolts thatextend transversely through slots 5 in the parts 2 and 2 and arecombined with said parts in such a manner that said fastening members f1can.

to provide each of'the fastening members al with a head et, as shown inFigs. 2, 3 and 4L, that is seated in a recess 5 formed in the parts 2with which said fastening member coperates, the companion part 2a beingprovided with a recess for receiving the nut lb on the opposite end ofsaid fastening member. Lugs G on the part 2 lap over the head 4 on thefastening member 1-, as shown in Fig. 2, La on the fastening member inthe recess f and prevent the fastening member +L from 'becomingcompletely detached from the part 2 when said fastening member is swungdownwardly into the position shown ,in Fig. lduring the operation ofremoving or inserting the inner tubel of the tire. Luge 61 on the part2aL coperate with the nut ab when the astening member L1 is arranged inoperative ositiongas shown in Fig. 3, o as to prevent. said 'A fasteningmember 4 rom swinging downwardly accidentally. A cover plate'1 7 on theportion 1 of the demountable rim that extends circumferen- A.'tiallyaround vsame acts as a closure for the so as to hold the head preventingdirt from becoming packed in .pt' the wheel the inner tube of the tirecan be removed easily from the outer casing without disconnecting theouter casing from the portions l and l of the demountable rim, by simplyloosening the nuts 4b on the fastening members sutliciently `to enablesaid fastening members to be swung into the position shown in Fig. l,thereby releasing 'the portion l of the deinountable rim and permittingthe two portions of the rim to be separated transversely. Gwing to thefact that the fastening members el are pivotally connected to theportion l of the demountable rim, there is no liability of saidfastening members el becoming lost during the operation of changing theinner tube ,of the tire. And still another desirable feature ot' such aconstruction is that it is not necessary to completely remove the nutsfl-b of said fastening members, this, of course, being due to the fact,that the fastening members 4. extend transversely through the slots 5 inthe cooperating parts 2 and 2a on. the demountable rim. 1f desired, thepart 21 can be provided with projections a1, `as shown in Fighthat enterrecesses y in the part 2 when the tvvo portions of the rim L are inoperative position, soas to prevent relative circumferential movement ofthe two portions l and Lt of said rim.

While l prefer to connect the two portions et the demountable rimtogether by fastening members which are arranged intransversely-disposed slots in said portions, I do` not wish it to beunderstood that my invention is limited to such a construction, for ifdesired, the two portions of the demountable rim could be; connectedtogether by transversely-disposed bolts l9 that extend through holesformed in the parts 2 and 2a of the rim, as shown in Fig. 7.

It is, oi' course, immaterial how the blocks 3 on the fixed rim. andthecoperating parts .2 and Qa on the demountable rim are formed, andwhile 'l prefer top ,construct said parts from blocks of solid metal,formed either integral with or detachably connected to the elements thatcarry same, they could, of cours consist of hollow members or pressedmembers.l as shown in Fig. 5, wherein the projections on the xed rimconsist of hollow members 13 connected to same in any suitable manner,and the cooperating parts' on the demountable rim consist of hollowmembers l2 and 12a connected to the two portions et the demountable rim.

Having thus described my invention, what l claim, and desire to secureby Letters Patent, is:

l, A dcmountable rim composed of' two laterally separable portionsprovided on their tions arranged in pairs, and transverselyn disposedadjustable fastening members arranged in open alining slots in saidcoperating projections.

Q. A demountable rim consisting of a longitudinally split member,transverselydisposed fastening devices that connect the two portions ofsaid member together, each of said fastening devices being providedinner sides with co eratinv` iro'ecwith a head at one endL that isarranged at j a right angle to the axis of said device, one

ot said portions being provided with lugs that lap over said head, and aplate on said portion that cooperates with the heads on all of saidfastening devices to prevent transverse movement thereof in one dire@tion.

3. A demountable rim, comprising a member that -is split longitudinallyat approxiu mately the center thereof and provided on its inner sidewith a plurality of projections having transversely disposed slots`lhcrem whose outer ends are enlarged, and
